PREPARATION OF SOME CYCLOPENTADIENYL TITANIUM COMPLEXES AND CRYSTAL STRUCTURE OF (ETA(5)-PENTAMETHYLCYCLOPENTADIENYL) ((1R,2S,3R)-EXO-3[(R)-2-PHENYL-2-OLATO-ETHYL] SULPHENYL-1,7,7-TRIMETHYLBICYCLO[2.2.1]HEPTAN-2-OLATO) CHLOROTITANIUM(IV) - [CP-ASTERI

摘要

The reaction of(1R,2S,3R)-exo-3 [(R)-2-phenyl-2-hydroxyethyl]sulphenyl-1,7,7-trimethylbicyclo[2.2.1]heptan -2-ol (1) with Cp(*)TiCl(3) in the presence of Et(3)N furnishes the product Cp(*)Ti(OC18H24SO)Cl in high yield {Cp(*) = pentamethylcyclopentadienyl; OC18 H24SO = (1R,2S,3 R)-exo-3[(R)-2-phenyl-2-olato-ethyl] sulphenyl-1,7,7-trimethylbicyclo [2.2.1]heptan-2-olato}. The structure of Cp(*)Ti(OC18H24SO)Cl . C6H6 (2) has been determined by X-ray crystallography. The reaction of Cp(2)Ti(X)Cl (X = Me, Cl) with 2-methoxybenzyl alcohol in the presence of Et(3)N under refluxing benzene gave the product Cp(2)Ti(X) (o-OCH(2)C(6)H(4)OMe) (X = Cl, Me).
